The correct expression for this question would be: (50+85)+ n(11+8). That is assuming that it was 50$ transportation for everyone, not 50$ per person (and also 85$).
Hope I was able to help! If you need any further assistance, please let me know and I will help you!
The vertices of the original quadrilateral can be written in matrix form using the vertex matrix. The vertex matrix is
To find the coordinates of the endpoints or vertices of the image of the given coordinate points reflected about the y-axis, we just need to multiply the transformation matrix by the vertex matrix. The transformation matrix for this particular problem is
Multiplying the two matrices, we have
Therefore, the coordinates of the endpoints or vertices of the image are
(5,4), (1,-1), (3, -6) and (7, -3).
Answer:
x = amount of 100% acid solution (pure acid, no water)
y = amount of 10% acid solution (acid + water)
<u>both amounts are in liters</u>
Step-by-step explanation:
Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction:
Step-by-step explanation:
<u>Percentages</u>
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% =
Simplifying by 5:
115% =
Summarizing:
As a percent: 115%
As a decimal: 1.15
